[0034] The embodiments of the present application are described in detail below, and the embodiments of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0035] In recent years, with the improvement of people's living standards, people have put forward higher requirements for the quality of drinking water. Therefore, water purifiers have been widely welcomed. However, existing water purifiers have no antifreeze measures. When the ambient temperature is low, the residual water in the water purifier is sealed in the internal pipes, and the water temperature drops and slowly freezes. The water in the water purifier will expand in volume due to freezing, causing the internal pipes to rupture and leak, causing safety accidents.

[0036] In view of the existence of the above-mentioned problems, the embodiments of the present application provide a water purification device and a control method, which control the water flow through a temperature sensor, a control valve and a controller, and conduct the heat or heat capacity generated when the water flows into the pipeline, thereby preventing the pipeline in the water purification device from freezing and cracking, ensuring safe use and improving product reliability.

[0037] See also Figure 1 , Figure 1 This is a schematic diagram of the pipeline of the water purification device provided in the embodiment of the present application. Figure 1 As shown, the water purification device 10 provided in the embodiment of the present application includes a first pipeline 100, a temperature sensor 101, a control valve 102, a filter 103 and a controller 104. The temperature sensor 101 is arranged in the first pipeline 100, and the temperature sensor 101 is used to detect the water temperature in the first pipeline 100. The control valve 102 is arranged in the first pipeline 100, and the control valve 102 is used to open or close the first pipeline 100. The filter 103 is communicated with the first pipeline 100, and the water flowing in from the water inlet side of the first pipeline 100 flows out from the water outlet side of the first pipeline 100 after being filtered by the filter 101. The controller 104 is connected to the control valve 102 and the temperature sensor 101 in communication.

[0038] The first pipeline 100 may be a main water pipeline of a water purifier. The water inlet of the main water pipeline is used to connect tap water, and the tap water flows in the main water pipeline and is filtered by a filter before flowing out of the water outlet of the main water pipeline to obtain pure water.

[0039] It is understandable that, since the municipal water pipe is buried underground, the water in the municipal water pipe generates heat or heat capacity when flowing, and then flows into the first pipe 100 in the water purification device 10, thereby preventing the pipe in the water purification device 10 from freezing and cracking, ensuring safety in use and improving product reliability. It should be noted that, since there are many people using water in the city, the water in the municipal water pipe flows continuously.

[0040] The working principle is as follows: Looking at the natural world, even in a scene of several degrees below zero, river water will not freeze, and well water is also difficult to freeze. It can be seen that when water flows, the friction between water molecules will generate heat energy. Regardless of whether this heat energy is converted into the heat or heat capacity of water, it will make the flowing water difficult to freeze. It can be seen that when the water purification device is in standby mode, the water enclosed in the first pipeline is connected to the municipal tap water pipeline. Since the water in the municipal tap water pipeline generates heat or heat capacity when flowing, it is transferred to the water retained in the water purification device, thereby preventing the pipes in the water purification device from freezing and cracking.

[0041] The control valve 102 may be a solenoid valve. A solenoid valve is a valve controlled by electric current. When the coil wire (also called an electromagnet) is energized, a magnetic field of a movable plunger is generated. The plunger moves to open or close the valve, allowing liquid or gas to flow through the valve or shut it off. That is, the embodiment of the present application can control water to flow into the first pipeline through the control valve.

[0042] The filter 103 may include a first filter, a second filter and a third filter which are sequentially connected through the first pipeline 100. The first filter may be a pre-filter, the second filter may be a reverse osmosis filter (RO membrane), and the third filter may be a post-filter.

[0043] The first filter can be used as a pre-filter, which includes a polypropylene (PP) filter element and an activated carbon filter element. The polypropylene (PP) filter element intercepts larger particle impurities in the water, such as mud, rust, etc., through its pore structure; the activated carbon filter element is known for its high adsorption capacity and can effectively adsorb free chlorine, odor, organic matter and other harmful substances in the water.

[0044] The pores on the polypropylene filter element filter out larger impurities, and the activated carbon filter element filters out free chlorine compounds and other free substances in the water. The pre-treated water can reduce damage to the second filter and increase its service life.

[0045] The second filter can be a reverse osmosis filter (Reverse Osmosis Membrane, also known as RO membrane). The RO membrane is driven by pressure to force a solution (such as water) to pass through a semipermeable membrane, thereby separating dissolved solids, bacteria, viruses and other impurities. The RO membrane is usually made of a variety of materials, including but not limited to polyamide, polysulfone, cellulose ester, etc. These materials have good chemical stability and mechanical strength. Among them, the RO membrane is a multi-layer cylindrical structure formed by winding, which increases the filtration area; and it can be detachably installed in the water purification device for regular replacement. When the pressurized water passes through the reverse osmosis filter (RO membrane), a part of the water can pass through the reverse osmosis filter (RO membrane) to obtain pure water, and the other part of the wastewater that has not passed through the reverse osmosis filter (RO membrane) is discharged from the drainage pipeline connected to the reverse osmosis filter (RO membrane).

[0046] The third filter can be used as a post-filter and can use large and small T33 filter elements. It can absorb the foreign color and odor in the pure water separated from the reverse osmosis filter (RO membrane), improve the taste of the water, and increase the nutritional mineral content in the water to obtain sweet pure water.

[0047] The controller 104 can communicate with the temperature sensor 101 and the control valve 102 by wireless connection or by wired connection. The controller 104 can be built into the water purification device 10 or can be an independent controller.

[0048] It should be noted that the temperature sensor 101 can monitor the water temperature in the first pipeline 100 in real time. When the temperature sensor 101 senses that the water temperature in the first pipeline 100 is lower than the first preset temperature, the controller 104 controls the control valve 102 to open so that water flows into the first pipeline 100. The first preset temperature can be set according to the actual needs of the product. When the temperature sensor 101 detects that the water temperature is lower than the first preset temperature, for example, lower than 0°C, it will send an abnormal signal to the controller 104. For example, if the temperature sensor 101 detects that the water temperature drops to -4°C, it will trigger the controller 104 to open the control valve 102 to allow the water to flow and prevent freezing.

[0049] The temperature sensor 101 continuously monitors the water temperature in the first pipeline 100 to ensure that abnormal temperature changes can be detected in time. When the water temperature drops below 0°C, for example -4°C, this is considered a potential freezing risk because the freezing point of water is 0°C. Once the water temperature is below 0°C, the temperature sensor 101 detects this change and sends this abnormal situation as a signal to the controller 104. After receiving the abnormal signal from the temperature sensor 101, the controller 104 will take immediate action. The controller 104 will instruct the control valve 102 to open and allow water to flow into the first pipeline 100. After the control valve 102 is opened, water begins to flow in the first pipeline 100, increasing the fluidity of the water and reducing the possibility of freezing of stagnant water.

[0050] Specifically, the temperature sensor 101 can monitor the water temperature in the first pipeline 100 in real time. When the temperature sensor 101 detects that the water temperature in the first pipeline 100 is below 0°C, for example, -4°C, the temperature sensor 101 sends an abnormal signal to the controller 104. The controller 104 controls the control valve 102 to open according to the received abnormal signal to allow water to flow in the first pipeline 100, so as to prevent water from freezing and avoid the risk of water pipe rupture.

[0051] In this way, the embodiment of the present application controls the water flow through the temperature sensor 101, the control valve 102 and the controller 104, and conducts the heat or heat capacity generated when the water flows to the first pipeline 100, thereby preventing the pipeline in the water purification device 10 from freezing and cracking, ensuring safe use and improving product reliability.

[0052] Optionally, in some embodiments, when the temperature sensor 101 senses that the water temperature in the first pipeline 100 is greater than the second preset temperature, the controller 104 controls the control valve 102 to close to prevent water from flowing into the first pipeline 100. The second preset temperature is greater than the first preset temperature. The second preset temperature can be set according to the actual needs of the product.

[0053] The temperature sensor 101 not only monitors low temperature conditions, but also detects in real time whether the water temperature in the first pipeline 100 is too high. The user can pre-set a second preset temperature, which is higher than the first preset temperature, and is used to determine when measures should be taken to prevent the risks that may be caused by excessive water temperature. When the temperature sensor 101 detects that the water temperature exceeds the second preset temperature, it will send an abnormal signal to the controller 104. After receiving the abnormal signal, the controller 104 will control the control valve 102 to close according to the preset logic. After the control valve 102 is closed, water can be prevented from continuing to flow into the first pipeline 100, thereby controlling the water temperature to no longer rise. In this way, the system can prevent the water temperature from being too high, which may have an adverse effect on the performance or water quality of the water purification device.

[0054] For example: the temperature sensor 101 can monitor the water temperature in the first pipeline 100 in real time. When the temperature sensor 101 detects that the water temperature in the first pipeline 100 is above 10°C, for example, 12°C, the temperature sensor 101 sends a normal signal to the controller 104. The controller 104 controls the control valve 102 to close according to the received normal signal to prevent water from flowing in the first pipeline 100.

[0055] Alternatively, in some other embodiments, see Figure 2 , Figure 2 Another schematic diagram of the pipeline of the water purification device provided in the embodiment of the present application. Figure 2 As shown, Figure 2 The water purification device 20 shown is Figure 1 The difference of the water purification device 10 shown is that Figure 2 The water purification device 20 shown also includes a timer 105, which is connected to the controller 104. The timer 105 is a device that uses a specific principle to measure time. The controller 104 can communicate with the timer 105 by wireless connection or by wired communication. Specifically, the timer 105 is used to record the first duration of water flowing into the first pipeline 100.

[0056] It should be noted that when the first time length is greater than the preset time length, the controller 104 controls the control valve 102 to close to prevent water from flowing into the first pipeline 100. The preset time length can be set according to the actual needs of the product.

[0057] For example, the timer 105 can record in real time the first duration of water flowing into the first pipeline 100. When the timer 105 detects that the first duration is more than 5 minutes, for example, 6 minutes, the timer 105 sends a normal signal to the controller 104. The controller 104 controls the control valve 102 to close according to the received normal signal to prevent water from flowing in the first pipeline 100.

[0058] The water purification device includes: a first pipeline, a temperature sensor, a control valve, a timer and a controller; the temperature sensor is arranged in the first pipeline, and the temperature sensor is used to detect the water temperature in the first pipeline; the control valve is arranged in the first pipeline, and the control valve is used to open or close the first pipeline; the controller is communicatively connected with the control valve and the temperature sensor; when the temperature sensor senses that the water temperature in the first pipeline is less than a first preset temperature, the controller controls the control valve to open so that water flows into the first pipeline. In this way, the present application controls the flow of water through the temperature sensor, the control valve, the timer and the controller, and conducts the heat or heat capacity generated when the water flows to the first pipeline, thereby preventing the pipeline in the water purification device from freezing and cracking, ensuring safe use, and improving the reliability of the product.

[0059] In some embodiments, the water purification device further includes a second pipeline, the second pipeline is connected to the filter, and the second pipeline is used to discharge the filtered waste water.

[0060] In some embodiments, considering that sometimes the water purification device is shut down due to power outage, if the temperature is low at this time, the controller cannot open the control valve normally due to the power outage, and the water in the municipal tap water pipe generates heat or heat capacity when flowing, which cannot be transferred to the water in the first pipeline, and then the first pipeline is frozen and cracked. In view of this, a backup power supply is provided inside the water purification device, and the backup power supply is electrically connected to the controller.

[0061] Among them, the backup power source is usually a battery, and there are many types of batteries, including lead-acid batteries, lithium batteries, and graphene batteries, etc. Considering the cost of the entire water purification device, the backup power source is preferably a lead-acid battery. At the same time, considering the volume of the water purification device, the number of lead-acid batteries is preferably 2 to 6 groups.

[0062] In some embodiments, the controller 104 is also used to periodically control the opening and closing of the control valve 102 so that water flows in the first pipeline 100 for a preset time. Specifically, the time for water to flow in the first pipeline 100 can be 1 to 10 minutes, that is, the time for water to flow in the first pipeline 100 can be preset manually according to actual needs. The controller 104 can also periodically control the opening and closing of the control valve 102 at intervals so that water flows in the first pipeline 100 for a preset time, wherein the interval time can be 5 minutes. For example, the controller 104 controls the control valve 102 to open for 2 minutes so that water flows in the first pipeline 100 for 2 minutes, and then the controller 104 controls the control valve 102 to close, and then opens the control valve 102 again after 5 minutes, and so on. The cycle allows water to flow periodically in the first pipeline 100, effectively preventing freezing and saving power consumption.

[0063] In some embodiments, the temperature sensor 101 can be arranged near the water outlet side of the first pipeline 100. Since the water outlet side of the first pipeline 100 is exposed to the environment, the temperature of the water outlet side is lower than the temperature of the water in the pipeline inside the water purification device 20, and it is easy to freeze. Therefore, by arranging the temperature sensor 101 on the water outlet side of the first pipeline 100, the abnormal water temperature can be monitored more timely and accurately, so that the temperature sensor 101 can send the abnormal situation to the controller 104 in a timely and accurate manner, and the controller 104 can open the control valve 102 in the first time, so that the water can flow in the first pipeline 100 in time to prevent freezing and cracking, thereby improving the safety and reliability of the product.

[0064] See also Figure 3 , Figure 3 This is another schematic diagram of the pipeline of the water purification device provided in the embodiment of the present application. Figure 3 As shown, Figure 3 The water purification device 30 shown is Figure 1 The difference of the water purification device 10 shown is that Figure 3 The water purification device 30 shown also includes a heater 106. The heater 106 is disposed in the first pipeline 100, and the heater 106 is used to heat the water flowing into the first pipeline 100. When replacing the low-temperature water in the first pipeline 100, the heater 106 is started to heat the water at the same time, so that the water temperature in the first pipeline 100 can be higher, so that the interval time of replacing water can be extended, and water can be saved.

[0065] The first pipeline 100 is provided with a water inlet, and the heater 106 is arranged near the water inlet. With such an arrangement, the water flowing into the first pipeline 100 can be heated in time, so that the water temperature in the first pipeline 100 is higher.

[0066] When the controller 104 controls the control valve 102 to open, the controller 104 simultaneously controls the heater 106 to heat the water flowing into the first pipeline 100 .

[0067] The water purification device provided by the present application includes: a first pipeline, a temperature sensor, a control valve, a heater and a controller; the temperature sensor is arranged in the first pipeline, and the temperature sensor is used to detect the water temperature in the first pipeline; the control valve is arranged in the first pipeline, and the control valve is used to open or close the first pipeline; the controller is communicatively connected with the control valve and the temperature sensor; when the temperature sensor senses that the water temperature in the first pipeline is less than a first preset temperature, the controller controls the control valve to open so that water flows into the first pipeline. In this way, the present application controls the flow of water through the temperature sensor, the control valve, the heater and the controller, and conducts the heat or heat capacity generated when the water flows to the first pipeline, thereby preventing the pipeline in the water purification device from freezing and cracking, ensuring safe use, and improving the reliability of the product.
